4.Manufacture

4.1The low-alloy ferritic steels may be made by the open-hearth,electric-furnace,or basic-oxygen pro-cess with separate degassing and re?ning optional.The basic-oxygen process shall be limited to steels con-taining not over6%chromium.

4.2The stainless steels shall be melted by one of the following processes:(a)electric-furnace(with separate degassing and re?ning optional);(b)vacuum-furnace;or(c)one of the former followed by vacuum or electroslag-consumable remelting.Grade F XM-27Cb may be produced by electron-beam melting.Because of dif?culties that may be met in retaining nitrogen, vacuum melting or remelting processes should not be speci?ed for Grades F XM-11,F304LN,F316LN, F304N,F316N,F XM-19,F44,F45,F48,F49,F50, F51,F52,F53,F54,F55,F58,F59,or F60. 4.3A suf?cient discard shall be made to secure freedom from injurious piping and undue segregation.

4.4The material shall be forged as close as practicable to the speci?ed shape and size.Except for?anges of any type,forged or rolled bar may be used without additional hot working for small cylindrically shaped parts within the limits de?ned by Speci?cation A234/A234M for low alloy steels and martensitic stainless steels and Speci?cation A403/A403M for austenitic and ferritic-austenitic stainless steels.Elbows, return bends,tees,and header tees shall not be machined directly from bar stock.

4.5Except as provided for in4.4,the?nished product shall be a forging as de?ned in the Terminology section of Speci?cation A788.

5.Heat Treatment

5.1After hot working,forgings shall be cooled to

a temperature below1000°F[538°C]prior to heat treating in accordance with the requirements of Table1.

5.2Low Alloy Steels and Ferritic and Martensitic Stainless Steels—The low alloy steels and ferritic and martensitic stainless steels shall be heat treated in accordance with the requirements of5.1and Table1.

itic stainless bar from which small cylindrically shaped parts are to be machined,as permitted by4.4,and the parts machined from such bar,without heat treatment after machining,shall be furnished to the annealing requirements of Speci?cation A479or this speci?cation, with subsequent light cold drawing and straightening permitted(see Supplementary Requirement S9if anneal-

ing must be the?nal operation).

NOTE1—A solution annealing temperature above1950°F[1065°C] may impair the resistance to intergranular corrosion after subsequent exposure to sensitizing conditions in F321,F321H,F347,F347H,

F348,F348H.When speci?ed by the purchaser,a lower temperature stabilization or resolution annealing shall be used subsequent to the initial high temperature solution anneal(see Supplementary Require-ment S16).

6.Chemical Composition

6.1The steel shall conform to the requirements as

to chemical composition for the grade ordered as listed

255in Table2.Test Methods,Practices,and Terminology A751shall apply.

6.2Grades to which lead,selenium,or other elements are added for the purpose of rendering the material free-machining shall not be used.

6.3Starting material produced to a speci?cation that speci?cally requires the addition of any element beyond those listed in Table2for the applicable grade of material,is not permitted.

7.Mechanical Properties

7.1The material shall conform to the requirements as to mechanical properties for the grade ordered as listed in Table3.

7.2Mechanical test specimens shall be obtained from production forgings,or from separately forged test blanks prepared from the stock used to make the?nished product.In either case,mechanical test specimens shall not be removed until after all heat treatment is complete. If repair welding is required,test specimens shall not be removed until after post-weld heat treatment is complete,except for ferritic grades when the post-weld heat treatment is conducted at least50°F[30°C]below the actual tempering temperature.When test blanks are used,they shall receive approximately the same working as the?nished product.The test blanks shall be heat treated with the?nished product and shall approximate the maximum cross-section of the forgings they rep-resent.

7.3For normalized and tempered,or quenched and tempered forgings,the central axis of the test specimen shall correspond to the1?4T plane or deeper position where T is the maximum heat-treated thickness of the represented forging.In addition,for quenched and tempered forgings,the midlength of the test specimen shall be at least T from any second heat-treated surface. When the section thickness does not permit this position-ing,the test specimen shall be positioned as near as possible to the prescribed location,as agreed to by the purchaser and the supplier.

7.3.1With prior purchase approval,the test speci-men for ferritic steel forgings may be taken at a depth (t)corresponding to the distance from the area of signi?cant stress to the nearest heat-treated surface and at least twice this distance(2t)from any second surface. However,the test depth shall not be nearer to one treated surface than3?4in.[19mm]and to the second treated surface than11?2in.[38mm].This method of test specimen location would normally apply to contour-

SA-182/SA-182M2001SECTION II

forged parts,or parts with thick cross-sectional areas where1?4T?T testing(7.3)is not practical.Sketches showing the exact test locations shall be approved by

the purchaser when this method is used.

7.4For annealed low alloy steel,ferritic stainless steels,and martensitic stainless steels,and also for austenitic and ferritic-austenitic stainless steels,the test specimen may be taken from any convenient location.

7.5Tension Tests:

7.5.1Low Alloy Steels and Ferritic and Martensitic Stainless Steels—One tension test shall be made for each heat in each heat treatment charge.

7.5.1.1When the heat-treating cycles are the same and the furnaces(either batch or continuous type)

are controlled within±25°F[±14°C]and equipped with recording pyrometers so that complete records of heat treatment are available,then only one tension test from each heat of each forging type(Note1)and section size is required instead of one test from each heat in each heat-treatment charge.

NOTE2—“Type”in this case is used to describe the forging shape such as a?ange,ell,tee,etc.

7.5.2Austenitic and Ferritic-Austenitic Stainless Steel Grades—One tension test shall be made for each heat.

7.5.2.1When heat treated in accordance with

5.1,the test blank or forging used to provide the test specimen shall be heat treated with a?nished forged product.

7.5.2.2When the alternative method in5.3.1is used,the test blank or forging used to provide the test specimen shall be forged and quenched under the same processing conditions as the forgings they represent.

7.5.3Testing shall be performed in accordance with Test Methods and De?nitions A370using the largest feasible of the round specimens.The gage length

for measuring elongation shall be four times the diameter

of the test section.

7.6Hardness Tests:

7.6.1Except when only one forging is produced,

a minimum of two pieces per batch or continuous run

as de?ned in7.6.2shall be hardness tested in accordance with Test Methods and De?nitions A370to ensure that the forgings are within the hardness limits given

for each grade in Table3.The purchaser may verify that the requirement has been met by testing at any

256location on the forging provided such testing does not render the forging useless.

7.6.2When the reduced number of tension tests permitted by7.5.1.1is applied,additional hardness tests shall be made on forgings or samples as de?ned in 7.2scattered throughout the load(Note2).At least eight samples shall be checked from each batch load and at least one check per hour shall be made from a continuous run.When the furnace batch is less than eight forgings,each forging shall be checked.If any check falls outside the prescribed limits,the entire lot of forgings shall be reheat treated and the requirements of7.5.1shall apply.

NOTE3—The tension test required in7.5.1is used to determine material capability and conformance in addition to verifying the adequacy of the heat-treatment cycle.Additional hardness tests in accordance with7.6.2are required when7.5.1.1is applied to enssure the prescribed heat-treating cycle and uniformity throughout the load.

7.7Notch Toughness Requirements—Grades F3V, F3VCb,and F22V.

7.7.1Impact test specimens shall be Charpy V-notch type,as shown in Fig.11a of Test Methods and De?nitions A370.The usage of subsize specimens due to material limitations must have prior purchaser approval.

7.7.2The Charpy V-notch test specimens shall be obtained as required for tension tests in7.2,7.3,and 7.5.One set of three Charpy V-notch specimens shall be taken from each tensile specimen location.

7.7.3The longitudinal axis and mid-length of impact specimen shall be located similarly to the longitu-dinal axis of the tension test specimens.The axis of the notch shall be normal to the nearest heat-treated surface of the forging.

7.7.4The Charpy V-notch tests shall meet a mini-mum energy absorption value of40ft-lbf[54J]average of three specimens.One specimen only in one set may be below40ft-lbf[54J],and it shall meet a minimum value of35ft-lbf[48J].

7.7.5The impact test temperature shall be0°F [?18°C].

8.Grain Size for Austenitic Grades

8.1All H grades shall be tested for average grain size by Test Methods E112.

8.1.1Grades F304H,F309H,F310H,and F316H shall have a grain size of ASTM No.6or coarser.

PART A—FERROUS MATERIAL SPECIFICATIONS SA-182/SA-182M

9.1Corrosion testing is not required by this speci?-cation.

9.2Austenitic grades shall be capable of meeting

the intergranular corrosion test requirements described

in Supplementary Requirement S10.

10.Cast or Heat(formerly Ladle)Analysis

10.1Each heat or furnace ladle of steel shall be analyzed by the manufacturer to determine the percent-age of elements prescribed in Table2.This analysis shall be made from a test specimen preferably taken during the pouring of the steel.For multiple-heat ingots, either individual heat analyses or a weighted average analysis may be reported.The steel shall conform to

the chemical composition requirements prescribed in Table2.

10.1.1If the test sample is lost or declared inade-quate for chemical determinations,the manufacturer may take alternative samples from appropriate locations near the surface of the ingot or forging as necessary

to establish the analysis of the heat in question.

10.1.2If consumable remelting processes are em-ployed,a chemical analysis made on one remelted ingot (or the product of one remelted ingot)per heat shall

be taken as the heat analysis,and shall conform to

the chemical composition requirements prescribed in Table2.For this purpose,a heat is de?ned as all of

the ingots remelted from a single primary melt.

11.Product Analysis

11.1The purchaser may make a product analysis on forgings supplied to this speci?cation.Samples for analysis shall be taken from midway between the center and surface of solid forgings,midway between the inner and outer surfaces of hollow forgings,midway between the center and surface of full-size prolongations,

or from broken mechanical test specimens.The chemical composition thus determined shall conform to Table2 with the tolerances as stated in Table4or Table5.

25712.Retreatment

12.1If the results of the mechanical tests do not conform to the requirements speci?ed,the manufacturer may reheat treat the forgings and repeat the tests speci?ed in Section7.

13.Workmanship,Finish,and Appearance

13.1The forgings shall be free of scale,machining burrs which might hinder?t-up,and other injurious imperfections as de?ned herein.The forgings shall have a workmanlike?nish and machined surfaces(other than surfaces having special requirements)shall have a surface?nish not to exceed250AA(arithmetic average)roughness height.

13.2At the discretion of the inspector representing the purchaser,?nished forgings shall be subject to rejection if surface imperfections acceptable under13.4 are not scattered but appear over a large area in excess of what is considered to be a workmanlike?nish. 13.3Depth of Injurious Imperfections—Linear imperfections shall be explored for depth.When the depth encroaches on the minimum wall thickness of the ?nished forging,such imperfections shall be considered injurious.

13.4Machining or Grinding Imperfections Not Classi-?ed as Injurious—Surface imperfections not classi?ed as injurious shall be treated as follows:

13.4.1Seams,laps,tears,or slivers not deeper than5%of the nominal wall thickness or1?16in.[1.6 mm],whichever is less,need not be removed.If these imperfections are removed,they shall be removed by machining or grinding.

13.4.2Mechanical marks or abrasions and pits shall be acceptable without grinding or machining pro-vided the depth does not exceed the limitations set forth in13.4.1.Imperfections that are deeper than1?16 in.[1.6mm],but which do not encroach on the minimum wall thickness of the forging shall be removed by grinding to sound metal.

13.4.3When imperfections have been removed by grinding or machining,the outside dimension at the point of grinding or machining may be reduced by the amount removed.Should it be impracticable to secure a direct measurement,the wall thickness at the point of grinding,or at an imperfection not required to be removed,shall be determined by deducting the amount removed by grinding from the nominal?nished wall thickness of the forging,and the remainder shall be

SA-182/SA-182M2001SECTION II

not less than the minimum speci?ed or required wall thickness.

14.Repair by Welding
